This Labor Condition Application (LCA) was filed by Mariana Oncology, Inc. for the position of Senior Scientist I, Biology in Watertown, Massachusetts. The offered annual salary is $133k, compared to the prevailing wage of $91k for this occupation and location. This represents a wage premium of +45.0% above the prevailing wage.
The LCA is the first step in the H-1B visa process. Employers must file an LCA with the Department of Labor certifying that they will pay the foreign worker at least the prevailing wage for the occupation in the area of intended employment. A certified LCA is required before the employer can file an H-1B petition with USCIS.
Case status: Certified. This means the Department of Labor has certified that the employer meets the wage and working condition requirements.
A Labor Condition Application (LCA) is a mandatory document that U.S. employers must file with the U.S. Department of Labor (DOL) before they can petition for a foreign worker under the H-1B, H-1B1, or E-3 visa categories. The LCA process was established under the Immigration and Nationality Act (INA) to protect both foreign and domestic workers by ensuring fair wages and working conditions.
When a U.S. company identifies a foreign national to fill a specialty occupation position, they must first obtain DOL certification through the LCA process before filing the H-1B petition (Form I-129) with U.S. Citizenship and Immigration Services (USCIS). In this case, Mariana Oncology, Inc. filed LCA case number I-200-23342-553882 to sponsor a Senior Scientist I, Biology position at their worksite in Watertown, Massachusetts. By filing this LCA, the employer attests to four key conditions: (1) paying the higher of the actual wage or prevailing wage, (2) providing working conditions that will not adversely affect other similarly employed workers, (3) no strike or lockout at the worksite, and (4) providing notice of the filing to the bargaining representative or posting notice at the worksite.
The DOL establishes four wage levels for each occupation and geographic area, representing the progression from entry-level to fully competent workers:
For this filing, the offered wage of $133k compares to the DOL prevailing wage of $91k for Biological Scientists, All Other positions in the Watertown, Massachusetts area. The positive wage premium of +45.0% indicates the employer is offering above the DOL-determined average for this occupation and location.
The prevailing wage is the average wage paid to similarly employed workers in a specific occupation in the area of intended employment. The DOL determines prevailing wages using data from the Occupational Employment and Wage Statistics (OEWS) survey conducted by the Bureau of Labor Statistics (BLS). Employers must pay H-1B workers the higher of the prevailing wage or the actual wage paid to other employees in similar positions at the company. This requirement is designed to prevent employers from using H-1B workers to undercut domestic wages.
A "Certified" status means the DOL has reviewed Mariana Oncology, Inc.'s attestations and determined that the LCA meets all regulatory requirements. The employer has demonstrated that the offered wage of $133k meets or exceeds the prevailing wage for Senior Scientist I, Biology positions in the Watertown, Massachusetts area. It is important to understand that LCA certification does not guarantee H-1B visa approval. The next step is for the employer to file Form I-129 with USCIS, which evaluates whether the position qualifies as a specialty occupation and whether the beneficiary has the required qualifications.
This LCA was received by the DOL on Dec 8, 2023 and a decision was rendered on Dec 15, 2023, a processing time of approximately 7 business days. The standard DOL processing time for LCA applications is 7 to 10 business days. This application was processed within the standard timeframe.

This position falls under SOC code 19-102900 (Biological Scientists, All Other), which standardizes how the Bureau of Labor Statistics classifies occupations across industries. Metropolitan areas like New York, San Francisco, and Seattle typically command higher salaries due to higher costs of living, while positions in smaller markets may offer lower nominal wages but comparable purchasing power.
